[PATCH] m68k{nommu}/blackfin : remove old assembler-only flags bit definitions.

[PATCH] m68k{nommu}/blackfin : remove old assembler-only flags bit definitions.

[Philippe De Muyter]

Long ago, PT_TRACESYS_OFF and friends were introduced as hard defines
to avoid straight constants in assembler parts of linux m68k.
They are not used anymore, and were not updated to follow changes
in linux kernel.  Remove them.  When similar constants are needed,
they are now generated using asm-offsets.c.

looks like it has always been dead code on the Blackfin side having
originated from the m68k port.

we can split the changeset to m68k & blackfin, or just let the m68k
guys run the thing through their tree.  i'm ok with it either way ...
i promise not to introduce conflicts into the blackfin file in the
mean time ;).
